You may receive this error when attempting to view or share a Powerpoint presentation in a Skype for Business Online Meeting:
"name.pptx" couldn't be converted for presentation because Visual Basic for Application (VBA) is not installed on this computer. Please install VBA and try again."
This is unfortunately caused by an invalid installation of Office. You will need to uninstall Office and re-install using the FULL download. Commonly caused by the "Click to run" or "streaming" installation of Office from Office 365.
This can also be caused by "Office 365 Home and Business". VBA is not included in this version.
